如何使用python 2.7将图片上传到google云存储

import os
from google.cloud import storage

def upload_image_to_gcs(bucket_name, local_image_path, gcs_image_path):
    # 设置Google Cloud Storage凭证路径
    os.environ["GOOGLE_APPLICATION_CREDENTIALS"] = "path/to/credentials.json"

    # 创建存储客户端
    client = storage.Client()

    # 获取指定的存储桶
    bucket = client.get_bucket(bucket_name)

    # 在存储桶中创建一个Blob对象
    blob = bucket.blob(gcs_image_path)

    # 上传本地图片文件到Google云存储
    blob.upload_from_filename(local_image_path)

    print("图片上传成功！")

# 调用函数进行图片上传
bucket_name = "your_bucket_name"
local_image_path = "path/to/local/image.jpg"
gcs_image_path = "path/to/gcs/image.jpg"
upload_image_to_gcs(bucket_name, local_image_path, gcs_image_path)
